INT blendop_new ( )

Creates a new blend table. This table will contain a blending effect, which you'll have to set afterwards, using the various functions. When that is done you can finally apply or assign the blend table to a graphic.

The source section of the blend table will be the normal object and the destination section will be cleared, removing translucency.

[edit] Returns

0	- Error: insufficient memory or the screen was not yet initialized.
!0	- Success (pointer to the blend table).

[edit] Notes

The right order of doing blending stuff: First create a new table with blendop_new(), then put a blending effect in it with for example blendop_tint(), and then assign it to a graphic with blendop_assign().

[edit] Errors

Insufficient memory

- There is insufficient memory available. This error doesn't occur often.

[edit] Example

Program test;
Private
    int blendTable;
Begin

    set_mode(320,240,16);

    x = 160;
    y = 120;

    graph = new_map(100,100,16);
    map_clear(0,graph,RGB(255,255,255));

    blendTable = blendop_new();
    blendop_tint(blendTable,1,255,0,0);

    Repeat
        if (key(_space))
            blendop_assign(0,graph,blendTable);
        else
            blendop_assign(0,graph,NULL);
        end
        frame;
    Until(key(_ESC))

OnExit

    unload_map(0,graph);

End

Used in example: set_mode(), new_map(), map_clear(), blendop_new(), blendop_tint(), key(), blendop_assign(), unload_map()

This will result in something like:

Blendops Functions

• Blendop_apply() • Blendop_assign() • Blendop_free() • Blendop_grayscale() • Blendop_identity() • Blendop_intensity() • Blendop_new() • Blendop_swap() • Blendop_tint() • Blendop_translucency() •
